NVIDIA Attack on Rambus Patent Among Requests Filed the Week of October 18^th

In their litigation/reexamination wars, Rambus and NVIDIA often look like two boxers trying to slug each other into submission.  That was true last Wednesday.  The same day that the PTO issued its Notice of Intent to issue a reexamination certificate, confirming the claims of Rambus’ U.S. Patent No. 6,715,020, NVIDIA requested another reexamination (Inter Partes Request No. 2 below).  The ‘020 patent is just one of 17 patents that Rambus has accused NVIDIA of infringing in their case pending in the Central District of California.  Five of those Rambus patents in litigation were the subject of a recently settled ITC investigation.  The ‘020 patent is related to Rambus’ U.S. Patent No. 7,209,997, which is also part of the California litigation and the subject of two pending reexaminations.  NVIDIA is now appealing the reexamination examiner’s decision to confirm the patentability of the ‘997 claims (95/000,471).

Reexamination Requests Filed the Week of July 5th

Here is the latest  installment of Reexamination Requests from Scott M. Daniels, of Reeaxamination Alert and Practice Center Contributor…

Reexamination requests are typically reported in the Official Gazette approximately three months after filing. Such a delay in reporting requests, particularly for requests that involve copending District Court litigation, is too long. We therefore report new ex parte and inter partes reexamination requests filed electronically the previous week as they appear on the Patent Office PAIR system.  Information on concurrent litigation is also provided, where available.

Some reexamination requests are still filed by paper.  Because of the time required for the Patent Office to review such paper requests before posting on PAIR, our report may come three weeks after filing.  The information available from the Patent Office may be incomplete in a few cases because not all the reexamination request papers have yet been posted on PAIR.  There may also be gaps in the Patent Office docket numbers listed because, for any of various reasons, a reexamination request has been assigned a docket number but is not ready for posting.
